The Lowdown
G’day, I’m Rusty, and after going over the numbers for Jaconé, here’s the read on the next 16 days.
We kick off Monday, July 20 with a clean morning. Waves are 6 ft from the ENE, period 7 seconds, with a light offshore breeze. The energy is moderate (421), and the surf is breaking clean. It’s a consistent break, so plenty of waves. The water temp is about normal for this time of year. The afternoon sees the swell drop to 4 ft and the wind goes cross-off, still fun but smaller.
Tuesday, July 21 is a repeat – morning offshore, 5 ft from the ENE, period 8 seconds, clean. Afternoon cross-off, 3 ft. Two solid days.
Wednesday, July 22 morning is smaller with 3 ft from the E, but the afternoon picks up to 4 ft from the ENE with a light cross-off breeze. Not the best, but workable.
From Thursday, July 23 through Sunday, July 26, it’s mostly poor. Onshore winds, lumpy, choppy. Saturday afternoon has a brief clean window with 4 ft S swell and cross-off wind, but it’s not the ideal direction.
Monday, July 27 is still messy with 6 ft to 7 ft SSE swell and onshore wind. Skip it.
Then Tuesday morning, July 28 – this is the standout. Glassy. Dead calm. A 6 ft SSE groundswell with 11 seconds and strong energy (875). The wind is zero, the waves are clean, and the long period gives them shape. The direction is off the optimum, but the quality is undeniable. Consistent, so you’ll get waves. This is the best session of the first week.
Tuesday afternoon holds the same swell but with a 20 km/h cross-off wind – still clean.
Wednesday, July 29 morning is still good with 5 ft SSE swell, 11 seconds, offshore NE wind. Clean and fun.
From Thursday, July 30 onward, the swell fades. Mornings are often clean with offshore winds, but the waves are small – 3 ft, 3 ft. Energy is weak. Monday, August 3 morning gives a surprise: 3 ft SSW swell, 11 seconds, gentle offshore – clean but small. The real second-week gem is Tuesday morning, August 4: 4 ft S swell, 13 seconds, offshore NNE wind, light breeze, energy at 529 (moderate). That’s a long-period groundswell, clean, and the best of the second week. The long period may make it a bit straight for the beach break, but it’s still a good paddle.
Best bets: Tuesday morning, July 28 for glassy perfection, and Tuesday morning, August 4 for a clean, long-period session.
This is Rusty, out.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
